 # Conencting to the University VPN
 
+To access some services within the university, you need to be on campus or connected to the university VPN.
+
+
+
 ## Chromebook
 
+First, you will need the AnyConnect extension. This can be installed from the play store: [https://play.google.com/store/apps/details?id=com.cisco.anyconnect.vpn.android.avf&hl=en_GB&gl=US](https://play.google.com/store/apps/details?id=com.cisco.anyconnect.vpn.android.avf&hl=en_GB&gl=US)
+
+You should see a page like this:
+
+![AnyConnect in the Play Store](images/vpn/play_store.jpg)
+
+After using the "Add to Chrome" button and waiting for installation, you will see the page changes to look like this:
+
+![AnyConnect in the Play Store](images/vpn/play_store_installed.jpg)
+
+You don't have to go through the play store to launch the VPN software in future. Once set-up, you will just need to click in the notification area and enable it.  For now, you can run it from the Play Store page, or use the search key on the Chromebook keyboard to find "AnyConnect", as in the screenshot below:
+

+
+You will see that the AnyConnect client is installed but might take a little time (no more than a minute or two) to be ready to use for the first time:

+
+When it's ready, you can click on the VPN icon in the notifications/settings tray accessed from the bottom-right corner of the screen:
+
+![VPN icon](images/vpn/vpn_toggle.jpg)
+
+Clicking on the VPN icon should give you the option to add a new VPN connection with the AnyConnect client.

+
+When you see this screen, you can click to add a new connection:
+
+![Client ready to add a connection](images/vpn/add_new_connection.jpg)
+
+This is where you enter the VPN server details. I've called it "Coventry University" here, which makes sense. You can call it something different, but ideally something that signifies what it connects to.  The address must be <tt>anyconnect.coventry.ac.uk</tt>
+
+This should now be saved so you can connect to it in future:

+
+To activate the connection, select it from the list. Here you will be asked for credentials. These are your university username and password.

+
+Once connected, you can see it shows in the AnyConnect dialog as well as in the notifications panel.
